Application filed June 14,

This invention relates to a life-saving de- Vice, and particularly to that class of lifepreserving devices adaptedto be fastened upon the body of'individuals to sustain them in the water in an emergency or for pleasure.-

The objects are to provide a life-saving device having several buoyant elements, in eluding inflatable tubes, whereby buoyancy is attained by reason of airin the" tubes, and

by reason of other elements, a further object 7 I beingito providea life-saving device that may be easily inspected to ascertain whether ef fective or defective. j 1 a Another object is to'provide a life-saving device that-is cheap to manufacture, easily adjusted to the body, and which is adapted to persons of different sizes.

Other objects are to provide a device of this character of arelatively large buoyancy capable of sustaining a swimmer in the water; which will adapt itself to his movements,

and not encumber his efforts, in reaching safety,and to provide a device that will lessen the liability to cold and cramps to the swim I accomplish the objects of my invention by the construction illustrated in the accoin panying drawing; I

In the drawing: Figure 1 is a top plan view of my improved life-savingdevice. Fig. 2'

is a front elevation of the device. Fig. 3'is a perspective detail view of the lower cork supporting band. Fig. 4 is an enlarged detail sectionalview of the device. a V In vpractice I provide a canvas fabric receptacle 11, made with a lower flange 12, provided with eyelets 13,-and having cord elements 14 at the center to divide the receptacle into compartments 15 and 16, and having the upper flanges 17 provided with eye lets 18. The material of which this compartment receptacle is made is waterproofed.

Within each compartment I provide the rubber inflatable tubesv 19, having projecting airvalves 20 wherebythey may be readily zinflated when the device is to be usedJ By providing two tubes, the device may be still effective if one tube shouldlose a portion of I c ing upwardlyffroin the receptacle, a cork its air. I provide shoulder straps 21 to as- I 59 sist'in locating and holding the device on r 'rosn cnr NAKA URA, on Los, ivcnnns nnionnra 'LIrE-sAvINelnnvI n storing andpacking purposes. in

lii l df ij lffl the body; the v les for adjustment .{I provideaporksupJ' porting band 23 which *is attachedfto fi'ange 12 by means of thegeyelets li Band 23 has' th ekfront portion24 in the-form of a fi *ifl i and havingoords 25m engage with loops 26 when adjustedto the user. On the upper: portion of band23, I mountanela'sticbelt 27, and on the inner face28 of the band,I

mount'the cork members29 and 30. These members'29 and 30 maybe. of cork material or any light waterproofmateriahand are l designed to-keepthe body-warm, and topre-- I vent chills or'cra 'nps. V i i a By providinga plurality of buoyant tubes, I provide safety in case one of theni'should become punctured; the remaining tube safe guarding the efficiency of the device. 1 The "elastic band 27 serves to maintain thedevice V insuitablearelation to thebody of the user, and the cork fibreelements 29 and 30' serve to v warm-the body of the user. Constructed as shown, this life-saving device is light, eflicient in use, easily adjusted I claim:

1. In a life-saving device, a substantially circularfabric receptacle, two inflatable rubber tubes mounted therein, one-"above the other, a depending flange onthereceptacle, a cork fibre supporting band attached to the. depending flange, an elasticbelt mounted on the upper portion of the supporting band, and a plurality of waterprooffibre elements mounted on the supporting band. C j 2. In. a life-savingdevice, a fabric recepy I a, V t acle, inflatable-rubbertubesmounted in the? j receptacle, a corkfibre supporting bandlde- 'a pending from the receptacle an elastic belt j mounted on the outer face ofthe supporting} f ,band, and a pluralitv of waterproof fibre eleri ments mounted on the inner face; of the sup-j porting band. l

tacle, inflatable rubber tubes mounted therein, v shoulderstraps niounted on and pro ect-1 seshoulder-strapshaving buclgk i i to thebody, does not interfere with the move- 5 5 H i "ments of the user, and may be deflated for '1. i

3. In alife-savingdevice, a fabric recepfibre supporting banddepending from tha J receptacle, a foldaible flap forming the front and loWer portion ofthe supporting band,

an elastic belt mounted on the upper portion of the-supporting band, and a plurality of Waterproof fibreelerhents mountedon the inner face of the supporting band.

4. Inelife-saving device, a fabric recep-' tacle, cords let the middle portion and dividing the receptacle into upper and lower compartments, inflatable rubber tubes, one

in each compatrtlnent adepending flange on r the receptacle, acork fibre supporting band secured to the'depending flange, ,anelastic 4 belt mounted on the upper portionof the supporting-band, and a plurality of Waiter proof'fibre elements mountedon the inner lface of'the supporting'band. P
